Description

Technical Field

[0002] Prefabricated and assembled concrete structure is a construction method that combines prefabricated components and on-site casting technology. This structure uses prefabricated concrete components or parts, which are assembled and poured with concrete on-site through steel bars, connectors or prestressed means to form a complete structural system. It combines the advantages of both cast-in-place and prefabrication technologies: reducing the use of formwork, reducing costs, and improving structural integrity and seismic resistance. In the field of civil engineering, prefabricated and assembled structures are becoming more and more popular due to their advantages.

[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figure 1-6 As shown, an embodiment of the present invention provides a prefabricated and assembled concrete structure joint deformation measuring device, including an X-axis measuring component 13, an insertion rod 18 is provided inside the X-axis measuring component 13, and one end of the insertion rod 18 is inserted into the interior of the prefabricated panel 1; it also includes an X-axis measuring component 27, an insertion rod 29 is slidably inserted into the interior of the X-axis measuring component 27, and one end of the insertion rod 29 is inserted into the interior of the prefabricated panel 22; the X-axis measuring component 13 and the X-axis measuring component 27 are used to detect the deformation amount in the X direction between the prefabricated panel 1 and the prefabricated panel 22; an adjustment mechanism 4, a Y-axis measuring component 5 and a Z-axis measuring component 6 are provided between the X-axis measuring component 13 and the X-axis measuring component 27; the Y-axis measuring component 5 is located on one side of the adjustment mechanism 4 and is distributed in parallel, and the Z-axis measuring component 6 is provided between the adjustment mechanism 4 and the X-axis measuring component 27; the Y-axis measuring component 5 and the Z-axis measuring component 6 are used to detect the deformation amount of the Y axis and the Z axis between the prefabricated panel 1 and the prefabricated panel 2, respectively.

[0026] In this embodiment, it includes an X-axis measuring component 3, which is an L-shaped structure. A through hole 31 is provided at one end of the X-axis measuring component 3, and a threaded sleeve 32 is fixed to the other end of the X-axis measuring component 3. The threaded sleeve 32 is threadedly engaged with the threaded rod 43. A reading instrument 33 is provided at one end of the X-axis measuring component 3 and is located above the through hole 31. A locking bolt 34 is provided on the outside of the X-axis measuring component 3 and passes through the through hole 31. The locking bolt 34 is used to lock the insertion rod 8 in the through hole 31, and the reading instrument 33 can be adjusted to the zero scale line on the insertion rod 8, that is, L0=0mm.

[0027] In this embodiment, an insertion rod 8 is provided inside the X-axis measuring component 3, and one end of the insertion rod 8 is inserted into the interior of the prefabricated plate 1; a limit plate 81 is fixed to one end of the insertion rod 8, and a scale bar 2 82 is provided on the outer wall of the insertion rod 8. The reading instrument 33 moves on the scale bar 2 82 and identifies the scale bar 2 82, thereby measuring the reading of the reading instrument 33 at the position of the scale bar 2 82. The structure of the insertion rod 2 9 is the same as that of the insertion rod 8, and the working mode of the X-axis measuring component 2 7 is the same as that of the X-axis measuring component 3.

[0028] This embodiment also includes an X-axis measurement assembly 2 (7). An insertion rod 2 (9) is slidably inserted into the interior of the X-axis measurement assembly 2 (7), one end of which is inserted into the interior of the prefabricated panel 2 (2). The structure of the X-axis measurement assembly 2 (7) is identical to that of the X-axis measurement assembly 1 (3). A reading instrument 4 (71) is located above the X-axis measurement assembly 2 (7), which can read the scale bar on the insertion rod 2 (9).

[0029] Specifically, the X-axis measurement component 1 3 and the X-axis measurement component 2 7 are used at least for detecting the deformation between the precast plate 1 and the precast plate 2 in the X direction; In this embodiment, an adjustment mechanism 4, a Y-axis measurement assembly 5, and a Z-axis measurement assembly 6 are provided between the X-axis measurement assembly 1 3 and the X-axis measurement assembly 2 7. The Y-axis measurement assembly 5 is located on one side of the adjustment mechanism 4 and is arranged parallel to the adjustment mechanism 4. The Z-axis measurement assembly 6 is provided between the adjustment mechanism 4 and the X-axis measurement assembly 2 7. Specifically, the adjustment mechanism 4 includes an operating head 41 located in the middle, and a number of rotating handles 42 are provided on the outside of the operating head 41. Threaded rods 43 are provided on both sides of the operating head 41. One end of the threaded rod 43 is threadedly sleeved with a sleeve 44. The rotation of the operating head 41 can drive the threaded rod 43 to rotate synchronously. The two threaded rods 43 rotate inside the sleeve 44 and the threaded sleeve 32 respectively, thereby realizing the change in length between the sleeve 44 and the threaded sleeve 32, so that the spacing between the insertion rod 2 9 and the insertion rod 1 8 can be adjusted, so that the insertion rod 1 8 and the insertion rod 2 9 are respectively inserted into the positioning hole 11 and the positioning hole 2 21.

[0030] Specifically, the Y-axis measuring component 5 includes a support plate 51 fixed on the outer wall of the X-axis measuring component 3, and a reading instrument 2 52 is provided at the end of the support plate 51. An ear plate 53 is fixedly installed on the outer wall of one side of the sleeve 44, and an insertion rod 54 inserted into the inside of the reading instrument 2 52 is provided on the outer wall of one side of the ear plate 53. As the sleeve 44 and the threaded sleeve 32 move, the insertion rod 54 moves inside the reading instrument 2 52, and the movement amount is measured using the reading instrument 2 52. As the adjusting mechanism 4 moves, the insertion rod 54 moves inside the reading instrument 2 52 along with the ear plate 53, thereby obtaining the adjustment amount of the adjusting mechanism 4. The vertical increase relative to the spacing value between the two positioning holes when the prefabricated plate is installed is the deformation amount of the Y axis.

[0031] Specifically, the Z-axis measuring component 6 includes a vertically distributed guide rail 61, and end covers 62 are provided at both ends of the guide rail 61, a scale bar 1 63 is provided on the outer wall of one side of the guide rail 61, and a slide groove 64 is provided on the outer walls of both sides of the guide rail 61. One end of the X-axis measuring component 2 7 is fixedly connected to a slider 65, and the slider 65 is slidably clamped on the outside of the guide rail 61. A reading instrument 3 66 is provided on the slider 65, and a fixing plate 67 is fixedly installed on the outer walls of both sides of the slider 65, and a locking bolt 2 68 is provided on the fixing plate 67. The locking bolt 2 68 can be used to lock the slider 65 and the guide rail 61, so that the device can be removed for reading, thereby improving the accuracy of the reading.

[0032] In this embodiment, the Y-axis measurement component 5 and the Z-axis measurement component 6 are used for detecting the deformation of the Y-axis and the Z-axis between the prefabricated panel 1 and the prefabricated panel 2, respectively.

[0033] In this embodiment, a positioning hole 11 is provided on the outer wall of one side of prefabricated panel 1, and a positioning hole 21 is provided on the outer wall of one side of prefabricated panel 2. The depth of positioning hole 11 and positioning hole 21 is at least five centimeters, which is conducive to the stable insertion of insertion rod 1 8 and insertion rod 2 9 into the interior of positioning hole 11 and positioning hole 2 21 respectively, thereby achieving more stable measurement operations.

[0034] It should be noted that the first reading instrument 33, the second reading instrument 52, the third reading instrument 66 and the fourth reading instrument 71 are all electronic digital reading instruments, which can intuitively read the test value of the deformation.

[0035] Working principle: After inserting the insertion rod 18 into the interior of the positioning hole 11, the vertical positioning reference L0 is measured by the reading instrument 133; then, by adjusting the position of the adjustment mechanism 4 and the Y-axis measuring component 5, the insertion rod 29 inside the X-axis measuring component 27 is inserted into the interior of the positioning hole 21. At this time, the value obtained by the reading instrument 252 is L1, the value of the reading instrument 36 is L2, and the vertical value of the reading instrument 471 is L3. The distance between L0 and L1 is the deformation in the X-axis direction (because when the precast plate 1 and the precast plate 2 were initially installed, they were in a parallel structure, that is, the misalignment in the X-axis direction was 0), L2 is the deformation in the Y-axis direction, and L3 is the deformation in the Z-axis direction. It should be noted that after the initial installation of prefabricated plate 1 and prefabricated plate 2, the offset distance in the X-axis direction is 0, the spacing between the positioning hole 11 and the positioning hole 2 21 in the Y-axis direction is a constant value Y0, and the offset distance between the positioning hole 11 and the positioning hole 2 21 in the Z-axis direction is 0.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
